Connecting .NET Lambda to Amazon Aurora PostgreSQL via RDS Proxy

Many organizations are modernizing legacy .NET applications while reducing database costs and enhancing scalability, particularly during migrations to AWS Lambda and transitions from SQL Server to Amazon Aurora PostgreSQL-Compatible Edition. The process involves connecting Lambda functions to Aurora PostgreSQL using Amazon RDS Proxy, with AWS Secrets Manager managing secure credential storage. The architecture includes a .NET Lambda function interfacing with Aurora PostgreSQL via RDS Proxy, which provides connection pooling to minimize database connection overhead. The solution requires a CloudFormation template to provision resources such as a VPC with private subnets, an Aurora PostgreSQL cluster, RDS Proxy, and Secrets Manager. The RDS Proxy is configured with parameters including PostgreSQL engine family, idle client connection timeout, and Secrets Manager secret. A Windows EC2 instance is provisioned, and access is facilitated through AWS Systems Manager Fleet Manager. The solution includes creating a sample table named "employee" in the database and a new .NET Lambda project that utilizes Npgsql for database connections. The Lambda function is deployed using the AWS CLI, and testing involves invoking the function and retrieving logs from Amazon CloudWatch. Finally, resources created during the process should be deleted to prevent ongoing charges.

Microsoft is rolling out a ‘turbo mode’ for Windows 11 installation as part of the big drive to fix the OS

Microsoft has enhanced the Windows 11 installation process by allowing users to bypass the update phase during setup, potentially reducing installation time by 20 to 30 minutes. This feature is currently being rolled out and enables users to pause updates indefinitely, a change from the previous maximum delay of five weeks. Users who skip updates during installation may miss crucial security fixes and features, leaving their systems vulnerable. A suggested approach is to use the skip feature during installation and then initiate updates once on the Windows 11 desktop. Some users have speculated that this decision may be influenced by the growing popularity of alternatives like Linux and Apple's MacBook Neo.

Original Windows Task Manager Was Just 80 KB, Says Microsoft Engineer

The original Windows Task Manager was 80 KB in size, while its current version is 4 MB. Dave Plummer designed it to remain operational during system freezes, emphasizing that every line of code has a cost. The Task Manager could manage multiple instances by sending private messages to existing ones and launching new instances if the original was unresponsive. It utilized global strings and direct access to the kernel’s process table for speed and efficiency. Users have noted that modern systems consume more resources for similar tasks compared to older versions like Windows 7.

Google Cloud Highlights Ongoing Work on PostgreSQL Core Capabilities

Google Cloud has made technical contributions to PostgreSQL, focusing on advancements in logical replication, upgrade processes, and system stability. Key developments include the evolution of logical replication towards active-active configurations with automatic conflict detection to identify row-level conflicts during replication. This progress has sparked discussions about consistency models in database systems. Enhancements have also expanded logical replication to include sequences, reducing manual synchronization needs. Improvements to pg_upgrade have streamlined large object management and reduced upgrade times, while ensuring WAL data retention and schema constraint preservation. Bug fixes have addressed issues with index pages, extension loading, and WAL flush logic. Future features under development include a structured conflict log for replication and enhancements to parallel data export in pg_dump.

Database Branching in Postgres: Git-Style Workflows with Databricks Lakebase

Database branching is a modern approach that addresses the limitations of traditional database management in development workflows. Unlike conventional database copies, which require significant time and resources to duplicate data and schema, database branching allows for the creation of isolated environments that share the same underlying storage. This method utilizes a copy-on-write mechanism, enabling branches to be created in seconds regardless of database size, with storage costs tied only to the changes made. Key features of database branching include: - Branch creation time: Seconds, constant regardless of database size. - Storage cost: Proportional to changes only, not the total data size. - Isolation: Each branch has its own Postgres connection string and compute endpoint. - Automatic scaling: Idle branches can scale compute to zero, incurring costs only when active. The architecture supporting this approach separates compute from storage, allowing multiple branches to reference the same data without conflict. This design facilitates time travel capabilities, enabling branches to be created from any point in the past for instant recovery and inspection. Database branching unlocks new workflows, such as: - One branch per developer, providing isolated environments for each engineer. - One branch per pull request, automating branch creation and deletion tied to PRs. - One branch per test run, provisioning fresh databases for each CI pipeline execution. - Instant recovery from any point in time within a designated restore window. - Ephemeral environments for AI agents, allowing programmatic database provisioning. Databricks Lakebase offers this database branching capability, transforming the database from a bottleneck into a streamlined component of the development process.

PostgreSQL logical replication: How to replicate only the data that you need

Many organizations using PostgreSQL face challenges in replicating data across different logical databases while controlling shared information. PostgreSQL 15 introduces native logical replication with column-level and row-level filtering within publications, allowing precise control over data transfer between PostgreSQL databases. Logical replication operates on a publish-subscribe model, where the source database logs changes to the Write-Ahead Log (WAL) and applies publication filters to transmit only the relevant data to the target database. Two filtering modes are available: column-level filtering allows users to specify which columns to replicate, while row-level filtering uses WHERE clauses to determine which rows to include. Both filtering modes can be combined in a single publication. The SQL syntax for creating publications and subscriptions is consistent across various PostgreSQL environments, with specific configurations required for enabling logical replication. Use cases for logical replication include multi-tenant SaaS data isolation, regional data distribution for ecommerce, PCI DSS compliance in financial services, development and testing environments, and retail inventory management. Prerequisites for implementing logical replication include using PostgreSQL 15 or later, ensuring network connectivity, having a user with replication privileges, enabling logical replication on the source instance, and monitoring WAL retention. Logical replication has limitations, such as the need for a replica identity for UPDATE and DELETE operations, the non-replication of DDL changes and sequences, and potential performance overhead during initial synchronization and ongoing replication. After testing, it is advisable to clean up by removing replication resources to prevent unnecessary costs.

Minecraft village features, loot, trades, and how to find them

Minecraft villages are important locations in the game, serving as resource-rich hubs for players. They can be found by looking for flickering lights at dusk or scanning for house silhouettes during the day. Players can also use specific seeds to locate villages directly. Villages contain various buildings, including libraries and cleric temples, which provide valuable resources like bookshelves and brewing stands. Villagers have specific trades that can be beneficial, such as: - Fletcher: Ideal for acquiring emeralds. - Librarian: Source of enchanted books. - Cartographer: Offers maps to mansions and oceans. Villagers can adopt professions when a profession block is placed nearby, except for Nitwits. Once traded with, a villager's trades remain fixed unless their profession block is removed. A list of villagers and their corresponding profession blocks includes: - Armorer - Blast Furnace - Butcher - Smoker - Cartographer - Cartography Table - Cleric - Brewing Stand - Farmer - Composter - Fisherman - Barrel - Fletcher - Fletching Table - Leatherworker - Cauldron - Librarian - Lectern - Mason - Stonecutter - Shepherd - Loom - Toolsmith - Smithing Table - Weaponsmith - Grindstone The fletcher is a good starting point for earning emeralds by trading sticks. Players can create and repeatedly break a fletching table to encourage trades. The librarian is crucial for obtaining enchanted books, with sought-after enchantments like Mending and Fortune linked to specific biomes. The cartographer offers maps to Woodland Mansions and Trial Chambers, which are essential for exploration.

I watched the first TV show ever based on a game and it made me realize: we’ve really got it good these days

The animated series Pac-Man, produced by Hanna-Barbera from 1982 to 1983, features characters such as Pac-Man, Ms. Pac-Man (Pepper), and Pac-Baby living in Pac-Village, which is governed by the Pac-President and protected by Super-Pac. The series includes antagonists like Mezmaron and a group of ghost monsters: Inky, Blinky, Pinky, Clyde, and Sue. Mezmaron seeks to capture Pac-Man for his knowledge of Power Pellets, which grow on Power Pellet Trees in the Power Pellet Forest. The show consists of 44 episodes over two seasons and often concludes with Pac-Man consuming the ghosts, who then return to Mezmaron in new ghost suits. The humor is aimed at children but lacks cleverness, and notable voice actors include Peter Cullen and Alan Lurie. The second season introduced a younger version of Pac-Man named PJ and increasingly bizarre plots.
